حلقات O-Rings من مطاط بونا-إن نيتريل | AS568-055 | داش 055 | صلابة 70 | أسود (30 / عبوة)

Replaced the worn seal on my pressure regulator with the AS568-055 and it fit perfectly with no leaks. The 70 durometer feels just right for a standard hydraulic application.

Pulled the 30-pack out of the bag and the 70 durometer hardness feels just right for snug seating without wrestling them into place. I swapped these onto a couple of pneumatic fittings and they sealed up first try, no leaks. Keep a box in the shop now for quick repairs.

The -40°F to +250°F rating is exactly what I needed for the hot oil line on my old compressor, and the 70 durometer feels firm but still seats easily without tweezers. Fit the groove perfectly on the first try and no leaks after a week of running.
